IMPROVEMENT IN Hose-c ouPLiNcs.

The Schedule referred to ln these Letters Patent and making of the lame.

To all whom it Imay conce/rnv:-Y

Bc it known that I, CONRAD LOCHER, of Oroville, in the county of But-teand State of California, have invented a'new and useful Improvement inHose-Couplings; and I do hereby declare that the following is a full andexact description .of the same,.

reference being had to the accompanying drawing and to the letters ofreference marked thereon.

` This invention relates to that class of hose-couplings which have theparts'united by means ot' segmental projections upon one part, andcorresponding grooves upon the other, and consists in certain details ofconstruction, which will be ti1llydescribedhereinafter. In the drawing#-Figure 1 represents an elevation, and

Figure 2, a sectional view of' the coupling. To enable others skilled inthe art tomake and use my invention, I will now proceed to describefully its construction and manner ot' operation.

A and B represent short metal `tubes, which bear a general resemblanceto each other, and are made tapering in form, with their lesser innerdiameter corresponding with the outside diameter of the hose to whichthey are to be applied, as is shown at la', fig. 2.

The part A is provided at its larger end upon its outer surface with twoor more segmental projections a a', which tit into corresponding grooves.b l upon the part B, the latter being formed in the overhangingproject-ions b b', as'clearly -shown infig. 2.

,The projections a a, are provided upon their rear sides with edgestaperingin both directions.

By means of this construction the'parts A B areunited by placing theprojections a c between the projections b l1', and turning the parts inopposite direc-tions either way.

By means ofthe tapering form of the projections a a, the partsaredrawn-closely together.

Into these tubes A B thc ends of the hose are introduced and fitted, theend in part B being caused to project a little beyond the line of theinner ring, as

shownat x, in order that both ends of the hose mayv areexpanded andsecurely held against displacement.

The thimble C is provided with au annular groove, c, ucar its largerend, 'beneath the projecting end of the hose, as is shown in iig. 2. Y

vSmall orices are made in the groove, which connect with the insideofthe thimble.

Bymeans ot' this construction the water or other duid, when the hose isin use, passes through these orifices and forces the projectingend ofthe hose tightly against the adjacent' end of the part A and forms aperfectly tight-joint.

yThis coupling can be instantly Ap-ut together or taken apart withwrench, Spanner, or other tool.

vI do not claim the elements" herein described in themselves, for I amaware that they are not new; but having thus fully describedmyinvention,

vWhat I claim as new, and desire to secure by Let-4 ters Patent, is vThe combination of the parts A and B, thimbles O and D, and the hoseends, t-he thimble C being provided with oritces for'admitting the waterbeneath the hose end to forma water-tight packing, as described.

This specification signed and witnessed this .27th day of September,1870.
